Is it just me, or does the PR experience with Github leave a lot to be desired? Unlike some, I don't have a problem with the concept of a PR per se, but I frequently find navigating the various conversations in my PRs more difficult than I feel it should be. If a branch is rebased, then comments on code that was changed get lost, and one has to go the Conversations tab and search for the comment there. I understand that the commit itself is gone, which is fine, but I think an easy way to navigate through the comments, even if their context is lost, would be a great improvement.
I am actually more interested in the suggestion to try VCS alternatives, though. To me, it seems like we have reached a local maximum with git where in principle, better approaches exist, but no one seems to think the cost of switching would be worth it.
